SPECIFICATION (forming part of Letters Patent No. 752,475, dated February 16, 1904. Application filed` September 8, 1963. SerialNu. 172,310. (No model.)

To a/ZZ whom it may concern:

Be it known that I, JOHNC.V SMITH, acitizen of the United States, residing at Perrysville, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Abrading-Tools; andI do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v

The invention has relation to an abradingtool, a tool designed for use in connection with sand or emery paper for rubbing down and smoothing oif Work.

The object of the invention is to provide a' tool of this character which shall be simple of construction, durable in use, and comparatively inexpensive of production and by the employment of which an uneven surface may be uniformly smoothed or rubbed over.

In the drawings, Figure l is aperspective View of my improved abrading-tool, one ofl .the cranks being shown in its folded position and the other in its `unfolded position ready for use. Fig. 2 is'a longitudinal sectional view. Fig. 3 is a cross-sectional view.

In the drawings, l denotes the body of thev tool, which has a flat base 2, provided with short bristle or brush 'tufts 2', forwardly and rearwardly projecting arms 3, and a handle or grip 4.

5 denotes rollers journaledjinthearms andY This 9 denotes pawls which f are adapted to eng Ge the ratchet-wheels and hold the rollers in their adjusted positions.` The cranks are preferably of the hinge type and when they are not in use are adapted to be folded down intothe position shown in Fig. 1, where they are out of the way and will not interfere with the work.

It is evident that a tool of this character will save much labor.

By providing the abradingstrip with a yielding backing, such as is furnished by the tufts 2', irregular or uneven surfaces may be as easily smoothed down as smooth surfaces, as the tufts tend to force the abrading-strip into the hollows of the material being worked upon and will yield to any projections-in the work and permit the abrading material to slide overthe same. In other words, the tufts act as an equalizing medium.

Itwill of course be understood that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacricing any of the advantages of this invention.

Having thus described my inventiomwhat I claim as new, and desire to secure by Letters Patent, is- Y An abrading hand-tool comprising a base having a handle on its upper sides and longitudinally-projectingarms at its ends, rollers revolubly mounted in said arms, means to rotate and means to lock the rollers, anda sheet of abradingy material extended under the base from end to end thereof and having its end portions reversely wound on the rollers. In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
